Variation de la morphologie de l’onde P<\/figcaption><\/figure>\n\n\n

On remarque sur ce trac\u00e9, une variation fr\u00e9quence d\u00e9pendante de la morphologie des ondes P.<\/p>\n

Ce rythme sinusal irr\u00e9gulier met en \u00e9vidence 2 groupes d’intervalles RR: l’un, court d’environ 260 ms et l’autre, long: 426 ms. Cela correspond respectivement \u00e0 des fr\u00e9quences de 135 et 85 bpm.<\/p>\n

Lorsque le tonus vagal s’exprime plus que le tonus sympathique (RR longs), l’amplitude des ondes P ne d\u00e9passe pas 2 mm (0,2 mV) et les sommets sont \u00e9mouss\u00e9s. A l’inverse, lorsque le tonus sympathique pr\u00e9domine (RR courts), on assiste \u00e0 une acutisation des ondes P; les sommets des ondes P deviennent pointus et l’amplitude atteint 5 mm (0,5 mV).<\/p>\n

Cette morphologie des ondes P, soumise \u00e0 l’influence du syst\u00e8me sympathique, rend parfois d\u00e9licat le diagnostic d’ ondes P pulmonaires.<\/p>","protected":false},"excerpt":{"rendered":"
